Description

The origin of this document is traced to a number of industry activities but focuses primarily on the evolving airspace operations to be implemented by NextGen and SESAR that appear feasible in the next decade.

From these inputs, the AEEC set out to define impacts to avionics architectures that would apply to in-production and in-service airplanes, recognizing that the impacts on the architectures would vary as a function of the existing avionics baseline.

The equipage impacts described in ARINC Report 660C are intended to provide the airlines with the necessary information to evaluate modernization proposals, and to support the overall goal of fleet commonality while meeting operational requirements.

Note that the descriptions in ARINC Report 660C reflect avionics architectures from a transport category airline perspective but may also have applications to the regional market in some respects. For example, Sections 2.0 (Introduction to NEXTGEN/SESAR Concepts) and 4.0 (Impacts on Airborne Functional Architectures) may be applicable to both the major and regional segments, while Sections 3.0 (Avionics Reference Architectures) and 5.0 (Recommended Avionics Architectures to Support NEXTGEN/SESAR) specifically speak to large transport category aircraft operators. Although unique military requirements are not addressed in this document, Military Transport Aircraft must satisfy the same requirements as commercial transport aircraft since most of their operations are in civil airspace.

Purpose

This document identifies and describes the aircraft avionics capability necessary for operation in the evolving Communications Navigation Surveillance/Air Traffic Management (CNS/ATM) environment expected for the FAA NextGen program, Single European Sky ATM Research (SESAR) program and considerations of the Japan Collaborative Actions for Renovation of Air Traffic Systems (CARATS). These capabilities are intended to satisfy the industry’s long-term CNS/ATM operational objectives.

The International Civil Aviation Organization (ICAO) Global Air Navigation Plan (GANP) (Doc 9750) is ICAO’s highest air navigation strategic document and the plan to drive the evolution of the global air navigation system, in line with the Global Air Traffic Management Operational Concept (GATMOC, Doc 9854) and the Manual on Air Traffic Management System Requirements (Doc 9882). Starting in 2020, the sixth edition of the GANP Doc 9750 document has been split into two separate levels: the Global Strategic Level and the Global Technical Level.

The Global Strategic Level is a document, written in executive language, which provides strategic directions for decision-makers. It has been made available via a printer-friendly, interactive, web-based platform on the ICAO GANP Portal.

The Global Technical Level of the GANP is comprised of the Aviation System Block Upgrade (ASBU) framework. It addresses airspace user needs, regulatory requirements, and the needs of Air Navigation Service Providers and Airports.

The ASBU defines target implementation timelines organized in four five-year blocks: Block 0 – 2013, Block 1 – 2018, Block 2 – 2023, and Block 3 – 2028 onward. Each Block addresses four aviation performance areas:

• Airport operations
• Globally-interoperable systems and data
• Optimum capacity and flexible flights
• Efficient flight paths
